- Implemented in r_debug_esil_* APIs - Support for step-into and continue - Expressions can be regs, numbers, math operations, ranges, comparisons.. - Honor dbg.prestep for stepping before or after analysing - read-write-exec watchpoints using native debug backend and esil emulation - OSX/iOS debugger error message is now nicer - anal/rpnesil renamed to esil - Add esi,edi in osx regprofile - Add r_cons_is_breaked() for consistency
